Humidifiers are used to add moisture to dry air. They can help someone dealing with congestion, dry skin, and sinus discomfort and also help with things that affect our day-to-day lives, like static electricity. Using a humidifier correctly can greatly improve the living conditions in a dry home.

Steps

Part 1

Setting Up Your Humidifier

1

Choose the right type of humidifier for your needs. There are many different types of humidifiers on the market, so finding the best humidifier for your needs and circumstances is very important. A few of the most common humidifiers include:

Central humidifiers. Central humidifiers are used to humidify an entire house. They are built into the house’s heating and cooling system.[1]

Evaporators. Evaporators are smaller humidifiers that use filters and fans to add moisture to the air. These types of humidifiers tend to be very affordable. [2]

Impeller humidifiers. Impeller humidifiers release a cool mist into the air. This is especially good news for people who have children in the house. These humidifiers use fast moving disks to release their mist, and they work best for single rooms. [3]

Steam vaporizers. Steam vaporizers heat up the water in the water reservoirs and the force the water to cool before releasing it into the air as a mist. These are the most economically friendly humidifiers, but they can release hotter mists, which can cause burns.[4]

Ultrasonic humidifiers. Ultrasonic humidifiers use vibrations to release moisture into the air. Since these come in both cool and warm mist variations, they are a good choice for a home with children. Pick one that is sized properly for your intended use and room volume and be aware that they will vary in cost depending on size and features.[5]

2

Read the humidifier manual. Humidifiers come in many styles, each with a set of recommended settings and care instructions. The instructions may differ from others you have owned so it is important to carefully read the instructions for your specific humidifier.

3

Assemble the humidifier if needed. With the help of the owner’s manual, put together any apparatuses that need to be assembled before your humidifier can be used. This can include things like adding wheels for mobility, basic assembly of the humidifier, or personal preference settings (such as the size of the mist opening).

Using Your Humidifier

1

Rinse out the water reservoir. Remove the water reservoir and clean it with mild soap and water before using the humidifier. This will clear out any residue from the manufacturing process, so you aren’t breathing those in when the humidifier is in use. 2.

2

Add water to the reservoir. Once the reservoir is cleaned, add in some distilled water.[6] Some humidifiers allow for tap water to be used, but distilled water is going to be free of any additives that tap water contains. There should be a marked water line on the water reservoir. Add the water up until this indicated water line.

If a filter must be added directly to the water, this is when to do so.

3

Position your humidifier. Your humidifier should be on a level, raised surface at least 12 inches away from walls.[7] Choose a spot that is high up with nothing underneath, like on top of a dresser. .

Don't place your humidifier underneath a shelf or near paper or curtains. Nearby objects tend to get dampened by the humidifier.

4

Turn on and adjust any settings. Plug in and power on the humidifier. Some humidifiers may have buttons or knobs that adjust the settings, so use these tools to change anything to your personal preference. If you are confused about what settings you should use or what any of the buttons or knobs mean, consult your owner’s manual.

Some humidifiers have a small space that allows you to add things like essential oils or vapor rub to the mist. This would be the time to add those items if desired. However, if your humidifier doesn’t explicitly say that it is compatible with those items, don’t use them.

When not in use, turn off the humidifier. The humidifier should not be going in an empty room.

5

Clean the humidifier regularly. A humidifier should be cleaned at least twice a week for regular users.[9] This will help prevent any bacterial growths from forming in the humidifier and in the water. For less frequent users, your cleaning habits should be very diligent, since bacteria and mold can grow between longer intervals of time between uses.

Water and mild soap work well for basic cleaning, but hydrogen peroxide and white vinegar can also kill bacteria.

Humidifier sizes are based primarily on the size of the space you wish to humidify. Most humidifiers have a square foot coverage measurement on the packaging that allows you to gauge which humidifier size would be best for you. Before purchasing a humidifier, measure the space you want to humidify so you have a idea of what size would be best.

Tips

Tap water has not been conclusively shown to cause health risks when used in humidifiers. Distilled water is simply a purer alternative that causes fewer complications with the humidifier apparatus.

Warnings

Do not allow the area around the humidifier to become damp. This encourages growth of mold and mildew.

Young people, elderly, and those with pre-existing lung conditions may be more susceptible than others to airborne bacteria, so it is important that humidifiers used around these populations be cleaned carefully and often.
